Submit the source code .java file(s) on Ecampus. It’s o.k. to combine the three questions into one compilable java file.
1. Create a program named sign.java. Ask the user which month and day they were born. Output their birthstone and zodiac sign. You should have these two methods in your program:
String Birthstone(int Month)
String ZodiacSign(int Month, int Day)
Example output:What month were you born (1-12)? 5
What day of the month were you born? 21
Your birthstone is Emerald.
Your zodiac sign is Gemini.
Challenge: Include the Chinese zodiac animal. This requires you ask ask the user for the year they were born.
2. Create a program named board.java. Create a 10×10 two dimensional array of characters. Fill all 100 elements with a period. Next, fill ten random elements with a plus symbol. Place your last name initial in a random location. Output the array using a nested for loop in this format:
. . . + . . . . . .
. . . . . . . . . .
. . . + . . . . . .
. . . . . . . . + .
. . K . . . . . . +

3. Create a program named roman.java. Ask the user to enter a Roman Numeral. Output the numeric value of the Roman Numeral. You should have the following method in your program:
int RomanToDecimal(String R)
Here’s some numbers to test your program with: MCMXLII = 1942, MCMLXIX = 1969, DCCCLXXXVIII = 888
Hint: In the RomanToDecimal method, create a for loop that steps through each character of roman numeral.
M = 1000, D = 500, C = 100, L = 50, X = 10, V = 5, I = 1.
MDCLXVI = 1000 + 500 + 100 + 50 + 10 + 5 + 1 = 1666
If a digit is out of order, then it is subtracted from the next digit. This is only used for these combinations:
CM = 900, CD = 400, XC = 90, XL = 40, IX = 9, IV = 4
